How to use the heavy metal detector 14 to detect heavy metal components in the liquid is a mature existing technology and will not be repeated here.

[0027] Specifically, the juice extraction mechanism 6 includes a juice extraction box 61 and a second electric telescopic column 62. The juice extraction box 61 is fixedly connected to the top of the screening cylinder 5. A feeding pipe 63 which is interconnected with the juice extraction box 61 is fixedly connected to the top of the juice extraction box 61. The top of the feeding pipe 63 passes through the outside of the outer shell 2. Vegetable and fruit materials to be tested for heavy metals can be added to the juice extraction box 61 through the feeding pipe 63 extending outside. A driving motor 64 is fixedly installed at the center of the top of the juice extraction box 61. The output shaft of the driving motor 64 passes through the inside of the juice extraction box 61. A plurality of crushing blades 65 are fixedly connected to the surface of the output shaft of the driving motor 64 located in the juice extraction box 61. The crushing blades 65 are driven to rotate by the output shaft of the driving motor 64 to extract juice from the vegetable and fruit raw materials.

Secondly, it can achieve efficient separation of solid and liquid, and facilitate the rapid removal of solid materials after juicing, thereby improving work efficiency and having high practicality.

[0030] When in use, the material to be tested for heavy metals is added through the feeding tube 63. After the material falls into the juicer box 61, the driving motor 64 is turned on, so that its output shaft drives the crushing blade 65 to rotate and fully chop the material. After completion, the valve on the discharge cylinder 66 is opened, and the solid material and juice fall onto the filter assembly 10 together. The solid impurities can be filtered out by using the filter cover 102. The juice enters the liquid collecting tank 11 through the liquid guide cylinder 103 and the liquid pipe 104, and enters the heavy metal detector 14 through the liquid outlet pipe 12 for detection. The solid material accumulates on the upper surface of the filter cover 102, and the first electric telescopic column 9 is opened. Afterwards, it can drive the filter assembly 10 and the solid material to move upward, so that the material flows out from the discharge port 7 and falls onto the material support plate 8 for collection. After opening the outer sealing door 4, the material can be quickly taken out through the material taking port 3. When the equipment needs to be cleaned, it is only necessary to remove the heavy metal detector 14 and add clean water through the feeding pipe 63. The second electric telescopic column 62 can drive the connecting plate 67 to move vertically. Under the connection of the bracket 68, it drives the scraper 69 to move vertically to clean the inner wall of the juice box 61. The cleaning water passes through the discharge barrel 66, the filter assembly 10 and the liquid collecting tank 11 in turn, and is finally discharged from the liquid outlet pipe 12.
